TTL output driver having an increased high output level |
摘要 |
A TTL output driver is provided which increases the high level of the output signal thereof. The first and second emitters of a first transistor are coupled to the collector and base of a second transistor, respectively, the emitter and collector of which are coupled to the output of the TTL output driver and through a series combination of diode and resistor to a source of operating potential respectively. The output voltage is increased by reducing the base current drive of the first transistor required to achieve the desired output current.
